sir, at 5:31 I am pretty sure that you do the price index of COMPONENT B but the question ask for COMPONENT C, haha the ans should be (110 x 140) / 100 =154 in SPM, can I use the smiley face method instead of the soooo complicated formula? thank you sir

Yes you are right again! Another student pointed out to me before. I will do an updated one this year. You can use smiley face method no problem. I don't like it because you memorize it instead of using logic. I discourage that in Mathematics where possible. I also teach my students the ratio method. If you understand ratios, it's very easy and can be applied to anything.
